Problem instaling F17 on a non-GPT partion label

I want to use dual boot win7 and fedora 17. Windows 7 doesn't accept GPT partitioning at install, so I have to use the old MBR/ms-dos partitions. but it seems Fedora doesn't support ms-dos because I get this error at install: " you have not created a bootloader stage 1 target device; sda5 must have one of the following disklabel types: gpt. "
Is there a solution?
